Title: Digital autograph system
Inventor: ONO YOSUKE
IPC: H04L9/14
Filed: 1994-03-03
Abstract: PURPOSE:To enable calculation and verification of digital autograph which do not depend on the computer architecture on both sides of signal transmission and reception by coding a document to uniformed expression within a predetermined digital autograph system and converting the document to a common pit string expression, then executing autograph calculation and autograph verification. CONSTITUTION:A transmission side device 8 duplicates the document and uses one thereof as a document and the other as an autograph. One of the duplicated documents is transmitted as the document via a communication device and communication path 7 to a reception side device 9 and the other is handed as the autograph to a coder 3. The coder 3 codes the document in accordance with International Standard Code ASN. 1 and hands the result thereof to an autograph calculator 5. This autograph calculator 5 calculates the autograph from the coded document and transmits the calculated autograph via the communication device and communication path 7 to the reception side device 9. The reception side device 9 receives both of the document and the autograph, hands the autograph to an autograph verifying device 4 and duplicates the document. The document is coded and the check of a transmitter and the presence or absence of the alteration of the document are executed.

Title: Traction drive transmission
Inventor: TAKEHARA TORU
IPC: F16H13/08
Filed: 1992-02-20
Abstract: PURPOSE:To reduce temperature rise of a traction transmission mechanism and the whole transmission during operation by using ball bearings of low torque and low heat generation as bearing used for supporting planet rollers. CONSTITUTION:A traction transmission mechanism 3 is provided with planet rollers 6 supported with one shaft, and a sun roller 7 in one body with the other shaft arranged in the center of revolution of the planet rollers 6.

Title: Variable input burner
Inventor: MATSUI YASUTSUGU
IPC: F23N5/00
Filed: 1984-02-24
Abstract: PURPOSE:To obtain the burning within the allowable range of steady burning even if a vaporized pipe is clogged by tar by providing a controller that sets the upper and lower limits, or at least the lower limit, of the ionic current which detects the burning state, and controlling the burning amount so that it may not be adjusted outside the specified tolerance. CONSTITUTION:As the liquid fuel supplied from a fuel supply pump 2 is vaporized in a vaporizing pipe 1 and discharged from the outlet of the vaporized pipe 1, it draws and mixes with the primary air in a throat 5, and pre-mixed flame is formed at a burner head 4. This type of flame is detected by using the rectified wave shape of the ionic current flowing in a flame rod 7, and the ionic current value is fed back to a controller 8 to adjust the burning amount. Since the lower limit of the ionic current value is memorized by the controller 8, even if the burning amount is reduced due to the clogging by tar and the ionic current becomes lower than normal, the controller 8 controls the actuation frequency of the pump 2 when the ionic current in fact steps over the lower limit of the normal burning range so that it may not be reduced more than that.

Title: Centrifugal spherical graphite casted pipe and manufacture
Inventor: RIO BEROTSUSHI
IPC: C21D5/00
Filed: 1983-03-01
Abstract: The cast tube (T) is subjected internally in a chill-mould (1) to the uniform spraying of water from 1000 DEG  C. approximately to 350 DEG C. approximately. Then it is extracted from the chill-mould and in a furnace is subjected to isothermal bainitisation maintenance, after which it is cooled in the atmosphere to ambient temperature. Without it being necessary to add expensive chilling elements, one thus obtains lightened tubes having very good mechanical properties and the ovalisation of which remains acceptable.

Title: Protecting method for semiconductor element
Inventor: NOMURA TOSHIHIRO
IPC: H01L23/28
Filed: 1983-03-03
Abstract: PURPOSE:To contrive to miniaturize the protecting structure for the titled element by a method wherein the height of a flow stop adjacent to said element, among the stops arranged in the outer periphery of said element respectively, is made lower than the height of the stop in the outer periphery. CONSTITUTION:The flow of resin 5 is inhibited by the flow stop 6 provided adjacent to the semiconductor element 1, and the flow of resin 3 by the stop 7 arranged in the outer periphery. First, the arrangement of the flow stop 6 inhibits the flow of the resin 5, therefore the resin 5 after hardening can be easily obtained in uniformity. Besides, since the flow of the rsin 5 can be inhibited, the adhesion force of the resin 3 to a wiring substrate 2 can be obtained sufficiently even with the flow stop 7 of a relatively small outer shape. Accordingly, there is a small area of occupation of the protecting resin to said element on the wiring substrate 2.

Abstract: PURPOSE: To secure picture quality and to suppress the increment of error rate of a transmission packet by interpolating an error in a frame in which it occurs. CONSTITUTION: A proposal time detection/generation circuit 1 calculates the TS of an input transmission packet, and sends it to a recording formatting circuit 2. The circuit 2 adds the TS on the transmission packet on memory, and stores plural blocks in the memory in two-dimensional fashion setting the packet as a unit of recording block, and performs error correction encoding in a direction independent from the bit system of the block. In such a case, an error correction code capable of reducing an error rate than the one obtained by the error correction code by found propagation quantity is used. The output of the circuit 2 is sent to a recording processing circuit 3, and modulation suitable for recording is applied, then, it is outputted. A recording head 4 converts the output of the circuit 3 into a magnetic signal, and records it on a recording medium 5.

Abstract: PURPOSE: To attain the communication of the terminal network controller or the speech of a telephone set automatically by releasing ineffective hook-off state with a howler tone from a telephone line. CONSTITUTION: When a howler tone is outputted to telephone lines L1, L2, a line monitor section 3 discriminates whether a telephone set 39 or a terminal network controller is in a hook-off state to activate a latching relay 1. When the terminal network controller 37 is in an ineffective hook-off state, a main control section 6 is reset and data of a data memory section 5 are reported to a center after resetting. When the telephone set 39 is in an ineffective off- hook state, the latching relay 1 is selected to the position of communication on the occurrence of a terminal call such as emergency information even when the telephone set 39 is hooked off to report the information to the center. When the telephone set 39 continues the hook-off state even after lapse of a prescribed time, it is reported to the center.
